Zusammenfassung:The invention relates to a method for nondestructively acoustically examining at least one region of a component of a turbomachine, wherein at least the following steps are performed: a) arranging a transmitter comprising a plurality of individual oscillators on the region of the component to be examined, b) introducing at least one ultrasound beam into the component by means of the transmitter, c) receiving at least one ultrasound beam reflected by the component by means of a receiver comprising a plurality of individual receivers and d) checking, on the basis of the received ultrasound beam, whether there is a deviation in the region of the component which characterizes a segregation. The invention further relates to a device for carrying out a method of this type.
